I just made a movie from the first part of the article I read. Here’s the rest, I don’t think you’ll be dissappointed.
More Dreadful than Man Can Imagine
Secondly, this fire is far more dreadful than man can imagine. The natural fire that we see during this life has great power to burn and torment. Yet this is not even a shadow of the fire of Hell. There are two reasons why the fire of Hell is more dreadful beyond all comparison than the fire of this life.
The first reason is the justice of God, which the fire serves as an instrument in order to punish the infinite wrong done to his supreme majesty, which has been despised by a creature. Therefore, justice supplies this element with a burning power, which almost reaches the infinite…
The second reason is the malice of sin. As God knows that the fire of this world is not enough to punish sin, as it deserves, He has given the fire of Hell a power so strong that it can never be comprehended by any human mind. Now, how powerfully does this fire burn?
It burns so powerfully, O my soul, that, according to the ascetical masters, if a mere spark of it fell on a millstone; it would reduce it in a moment to powder. If it fell on a ball of bronze, it would melt it in an instant as if it were wax. If it landed on a frozen lake, it would make it boil in an instant.
Pause here briefly, my soul, and answer a few questions I will put. First, I ask you: If a special furnace were fired up as was customarily done to torment the holy martyrs, and then men placed before you all kinds of good things that the human heart might want, and added the offer of a prosperous kingdom – if all this were promised you on condition that for just a half-hour you enclose yourself within the furnace, what would you choose?
A Hundred Kingdoms
“Ah!” you would say, “If you offered me a hundred kingdoms I would never be so foolish as to accept your brutal terms, regardless of how grand your offer might be, even if I were sure that God would preserve my life during those moments of suffering.”
Second, I ask you: If you already had possession of a great kingdom and were swimming in a sea of wealth so that nothing was wanting to you, and then you were attacked by an enemy, were imprisoned and put in chains and obliged to either renounce your kingdom or else spend a half-hour in a hot furnace, what would you choose? “Ah!” you would say, “I would prefer to spend my whole life in extreme poverty and submit to any other hardship and misfortune, than suffer such a great torment!”
**A Prison of Eternal Fire
Now turn your thoughts from the temporal to the eternal. To avoid the torment of a hot furnace, which would last but a half-hour, you would forgo all your property, even things you are most fond of; you would suffer any other temporal loss, however burdensome. Then why do you not think the same way when you are dealing of eternal torments? God threatens you not just with a half-hour in a furnace, but with a prison of eternal fire. To escape it, should you not forgo whatever He has forbidden, no matter how pleasant it can be for you, and gladly embrace whatever He commands, even if it be extremely unpleasant?
A most terrible thing about Hell is its duration. The condemned person loses God and loses Him for all eternity. Now, what is eternity? O my soul, up to now there has not been any angel who has been able to comprehend what eternity is. So how can you comprehend it? Yet, to form some idea of it, consider the following truths:
Eternity never ends. This is the truth that has made even the great saints tremble. The final judgment will come, the world will be destroyed, the earth will swallow up those who are damned, and they will be cast into Hell. Then, with His almighty hand, God will shut them up in that most unhappy prison.
From then on, as many years will pass as there are leaves on the trees and plants on all the earth, as many thousands of years as there are drops of water in all seas and rivers, as many thousands of years as there are atoms in the air, as there are grains of sand on all the shores of all seas. Then, after the passage of this countless number of years, what will eternity be? Up to then there will not even have been a hundredth part of it, nor a thousandth – nothing. It then begins again and will last as long again, even after this has been repeated a thousand times, and a thousand million times again. And then, after so long a period, not even a half will have passed, not even a hundredth part nor a thousandth, not even any part of eternity. For all this time there is no interruption in the burnings of those who are damned, and it begins all over again.
Oh, a deep mystery indeed! A terror above all terrors! O eternity! Who can comprehend thee? **
- apart from that, the ideas were no different from those in many other writings of the same kind. I can’t say it bothered me at all. What was especially disappointing, all the more so given that the man was a Catholic bishop and is a Saint, was the almost complete absence of anything to suggest he was talking about something involving God: the anguish described was so relentlessly concerned with mere bodily pain, that he could almost have been talking about being burned alive on earth; which must be an agonising experience 
But no amount of bodily pain will prevent our being damned.
